Sorbitol Dehydrogenase (SDH, SORD, SORD1, L Iditol 2 Dehydrogenase, L-iditol 2-dehydrogenase)

Sorbitol dehydrogenase (SDH), a member of the medium-chain dehydrogenase/reductase protein family and the second enzyme of the polyol pathway of glucose metabolism, converts sorbitol to fructose strictly using NAD(+) as coenzyme.\nSorbitol dehydrogenase catalyzes the interconversion of polyols and their corresponding ketoses, and together with aldose reductase makes up the sorbitol pathway that is believed to play an important role in the development of diabetic complications. The first reaction of the pathway (also called the polyol pathway) is the reduction of glucose to sorbitol by ALDR1 with NADPH as the cofactor. SORD then oxidizes the sorbitol to fructose using NAD(+) cofactor. It has been noted that the polyol pathway is particularly active in hyperglycemic states. Although SORD is closely related to the class I long-chain alcohol dehydrogenases, it differs in substrate specificity, catalyzing polyols such as sorbitol and xylitol but having no activity towards primary alcohols.\n\nApplications: \nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
